§ Mr. Kilfoyle
To ask the Minister for the Cabinet Office for each year between 1992 and 2000, how many(a) people were seconded to the senior civil service from the private sector and (b) senior civil servants were seconded to the private and voluntary sectors; what the average length of their secondment was in each case; and how many (i) senior civil servants and (ii) permanent secretaries were on performance related pay. 
§ Mr. Stringer
Information on secondments of senior civil servants by sector is not held centrally. Information held by the Cabinet Office Interchange Unit relates to overall instances of Interchange activity across Departments. The Interchange Unit does not hold information on the length of individual secondments.
In 1998–99 there were 343 instances of Interchange (with all sectors) at senior civil service level. In this period there were (at all grades) 905 instances of Interchange between the civil service and the private sector, and 278 instances of Interchange between civil service and the voluntary sector.
In 1999–2000 these figures rose to 354 instances of Interchange at senior civil service level, 981 instances of Interchange with the private sector and 525 instances of Interchange with the voluntary sector.
All senior civil servants are on performance-related pay.145W
